LONDON, Jan 18 (Reuters) - German energy bourse EEX was forced to cancel an auction of 4.02 million spot EU carbon permits from the 2013-2020 trading phase on behalf of Germany on Friday after the reference price was not reached, underscoring weak demand that has slashed carbon prices.

LONDON, Jan 18 (Reuters Point Carbon) – European carbon prices plunged by as much as 10 percent on Friday after energy bourse EEX cancelled a German auction for 4 million EU Allowances, citing a lack of demand.

The city’s murder rate spiked 66 percent in the first quarter of 2012, when temperatures were 30 percent above normal and snowfall was 30 percent below average. Unseasonably mild weather sends more people outdoors, helping to trigger more violence, Police Superintendent Garry McCarthy said in an interview.
